Reference may be had to Patent No.` 919,656,issued April 27, 1909, to Burroughs Adding Machine Company, on the joint invention of Jesse G. Vincent and myself, for many particulars of the duplex accumulator construction which is vshown in the accompanying drawings, and reference may fur-v ther be had to Patent No. 924,118, issued June 8, 1909, to Burroughs Adding Machine Company, on the joint invention of said Vincent and Russell E. Benner', for certain particulars of mechanism shown in the accompanying drawings for automatically lically to some of the features already known y in making clear the manner of coopera-tion therewith of the novel features I have devised. y

Depressible amount keys 291 control the racks 610 as usual and the two sets of pinions 916 and 916a are carried as heretoforein separate rock frames. Pit-men 914 and 914.-a control t-he rock frames respectively as heretofore and a lever 10 determines how this control shall be exerted, said lever being coupled to the total key link 911 'as' heretofore and carrying a spring slide 13 witha lstud 19 to alternately engage raised edges u and t of the pitmen. The lever 10 is here shown witha stud 10c at its lower end adapted to alternately pass below undercut portions u2 and t of the pitmenpabeing an equipment of the said lever andlinvolving special formation of the pitmen not disl .closed in said Vincent-White patent but at ,the same time not claimed herein.

The transfer total key 265T operates as in the VincentWVhite construction `to lift the roller 19 out of contact with whichever pit-man it may be engaging and also operates as therein explained to pull down the total key. The manner in which depression Iof this-transfer total key causes one set of pinions to engage the racks during their descent and the other `to engage during their ascentI is fully set forth in said Vincent-White patent and need not 'he repeated here except to advert to the circumstance that according to the Vincent-White construction one .setof pinions disengages from the racks while the other set of pinions is moved intoengagement therewith.

Now referring to the irst-stated object of .the invention, which is to remove the possi bility of racks and pinions getting out of proper relationship for engagement, the constructionhere shown provides for transfer of totals only from the upper to the lower set of pinions and not vice versa, and further provides for fully engaging thelowel' set of pinions with the racks before the upper set of pinions starts to disengggage from the racks. Thus instead of havin-g the upper `,pinions disengaged and the lower pinions engaged as the handle of the machine starts rearward, provision is made for engaging the lower pinions with the racks at the end of the forward stroke of the operating handle. This entails modification in the control of the pitmen. Thus while the pitman 91/1 is pivotally connected as usual to the depending arm of the three-armed rock lever 913. the other pitman 914El is4 not1 so connected but is pivoted to a separate formed below the point of attachment of the inafter explained.

pitman 914, being bifurcated and having a widened foot e to the rear of the bifurcationy f and an elongated finger g at the front side of said slot. Normally the stud d 'seats in the upper end of the slot f as shown inf-Fig.

1 so that the three-.armed lever 913 and the rocker arm 913a are connected to move asl one. As a result of depression of the transfer total key 265T and an operation of the machine said stud is moved down out of said slot, thereby disconnecting said lever and arm so that the latter may move independently and it will be so moved by a stud 7i on a branch of the familiar vibrating arm or lever 813 as the latter arrives at the end of its rearward` swing which corresponds with the forward stroke of the operating handle, said stud 7L acting aga-inst a shoulder i of the coupler-slide 913". The effect is to draw thevlower pinions 916a into engagement with the racks, assuming the lever 10 to be in a position which would canse the upper pinions to engage the racks during their descent, wl1icl1,condition is compelled as here Therefore the lower pinions will be brought into full engagement with the racks while the upper pinions are still engaged therewith for the latter cannot be disengaged until the handle starts rearward and the wipe pawl 821 acts upon the stud. 961a in the usual mannerto shift the three-armed lever 913 and thereby rock the upper pinion frame rearward aft its lower end and forward at its upperend`l the pitman 914 being` then engagedv withl the lower stud of Said frame as shown in Fig. 4. The means for effecting the disconnection of the lever 913 and arm 913 and the interposition of the coupler shoulder 'i into the path of the stud L, are of the following de-' scription: A' lever suitably pivoted at its rear end to the frame-work as shown at j has an upper forwardly-extending branch 913 with a bifurcated end embracing the stud c of theconpler-piece 913" and .said arm of the lever carries a stud c in line with a footformed upon a depending portion 265a of the transfer total key stem 40 so that upon depression of said key the lever will be lowered. This lowering of the lever and consequent downward movement of the coupler-piece 913b is not sntiicient, however. to move the stud d out of the slot f as of course this should not take place until that stageA in the operation ofthe machine is reached where the lower pinions are tobe engaged with the racks. The lever has a lower 'downwardly and forwardly-extending branch 913d which isrformed with a beveled endedge m normally above .the line of travel ofV the stud k but adapted through movement of the lever caused by depression of the transfer total key, to 'enter the path of movement of said stud. The result is that as the arm 813 swings rearward the stud rides upon said beveled edge and' further lowers the lever, carrying the stud d of the couplerslide 913i out of the slot f, the stud L then landing against the shoulder i and moving the arm 913B asbefore described and with the eifect stated. The stud d remains under the foot e @so that when the three-armed lever 913 is shifted as the handlestarts' rearward the slot f will be again brought in line with said stud whereupon a spring 913e applied to the lever 9130-9131 pulls the same up and restores the parts to normal.

. As the above-describedconstruction only provides for transfer of totals from the upper to the lower set of pinions means are provided for preventing depression of the transfer tota-l key when the lever 10 is in a position which, under the arrangement shown in the Vincent-White patent, would cause a transfer from the lower to the upper set of pinions with the transfer total key depressed. Thus the upper end of the lever 10 is engaged with a sliding lock strip 40a arranged between the two keyboard plates 212 and Q13 and slotted to embrace the stem 40 of the transfer total key. This stem has ya notch 40h which, when the lever l0 swings' forward as to its upper end, is entered by a portion of the lock slide 40, as illustra-ted in F ig. 5, so that the key cannot be depressed with said lever 10 so adjusted.

Next. referring to the second'object stated, to-wit that of preventing disturbance of one set-lof pinions by reason of racks being r out of normal as a result of transfer tripping by the other set of pinions, this object is attalned by preventing successive operations of the. machinewith the transfer total key or the total or sub-total key held down between operations. At the conclusion ot' such a total transferring operation as above described the, upper set of pinions will be out of mesh with the racks Iand if the transfer total key or other to-talkey were left down and the handle again lpulled these upper pinions 'would immediately move into` engagement with the racks and should the latter have partaken of transfer movements as a result of addition of a transferred'total to a registration alread on the lower pinions, the dropping of t 1e racks to or beyond `normal would result in a backward turning of the upper pinions creating a false registration thereon, Therefore provision.

' sidered as part 'of a prime mover of the masprings which normally hold up the totall ismade for compelling-release of total keys between. operations. The tot-al key lever 227 is as Vusual linked to an arm which is secured to a rock vshaft y51 extending tojthe lon the i familiarv full-stroke sector 311, the

latch being beveled beyond saidn'shoulder. Aspring tends to create such engagement but is inferior to It-he spring 53 or other key. In addition tothe restraint imposed on the latch lever by engagement therewith 1 of the said arm 52, it is normally'engaged by. a detentlever 56-whose 'upper arm is formed to engage behind 'a stud 54a' on.a forward branch of the 'latch lever and whose downwardly-extending arm lies in-the path of the stud 311a with its upper edge on an.

inclination so that upon` operation of the machine said stud wipes over such edge and displaces the d tent lever ,against the stress n of the spring 54 which connects it with the latch lever. I, in this operation, the arm 52 is-rearwarduisa result'of depression of a total4 key the release of the latch lever by the displacement of the detent lever in addi--A tion tol the removal of restraint normally. imposed upon the latchlever by fthe'arm'52,4

results in ,the latchlever swinging forward as to its lower end ,so that upon the upward v struct1ons 1t will be obvious -that theclutch rockingif the-full-stroke sector 311 to normal its stud 311a willl wipe over the inclined lower edge of the latch lever and the shoulder ofthe latter will-then spring under said stud preventing another operation of the machine untilthe depressed total key hasV been released, (see Fig. 15) Of course upon V.the 'release'of such depressed total kevl-t'he the starting device employed when the mai chine is power-driven. In Figs.- 2l and 15 I have illustrated an electric' ''drive attach; ment such as disclosed in'P'atent No. 866,7 50,`

. arm 52 swings-forward, vforcing the 'latch c lever lback to normal ori to the position shown in Fig. 2, whereupon the detent lever 56 becomes rengaged with it.

In addition to the above-described locking of the full-.stroke sector, which may be conchine, provision is also made for locking issued September' 24, 190'?,v to Burroughs Adding. Machine Company, on the invent-ion of Jesse G. Vincent, with some modification in construction to provide for control by the latch lever 54. lThus Athe lever 80 which supports one end of the starting bar 81, is

end of which foot stands4 normally just above roesgaeev ofthe said latch lever as shownin Fig. 2. The result is that' when the latch lever` moves to its effective position illustrated 1n l*`1g.

.15 said stud 54b passes 'under said foot and prevents a second depression of the starting bar so long as the total keyrelnains de- ,.pressed. The vertical bar or link 84 1s `modified in construction by a shortening of the slot 84a at the upper end thereof so that when said vertical bar orlink'is depressed' by the roller Astud 31 1b.on.theAfull-stroke secand Yrearward of a stud 54bat the upper end `tor 311y the starting bar lever `80v wllbe forcibly raised far enough to carry the foot- 82 above .the stud 54b so vthatthe latter will be free to pass 'under the foot asI the opera'- -tion of the machine proceeds.

In Fi .`16 there is illustrated a modification of t e construction last above described.

Here the slot at the upper end of the vertical bar or link ..84 is not shortened and `Vso' there is not the .forcible return of the starting bar 81 and the latter is not itself .locked butv instead the bar or link 84 is locked.

Thus the -latter is' formed with a forwardlyextending branch 84h with a raised portion at its forward 'extremity having a curved ,upper edge, and the lower end of the latch lever 54 has a laterally-projecting stud 542-;

. When the latch lever swings to effective po?,

sition, such .as illustrated' in Fig. 15, this stud 54'moves over the raised portion of said'branch-of the bar or link 84, thereby locking the'latter against the upward movementnecessary for closing the clutch.

With either of the above-described "conof the electric ldrive. cannot be. closed im mediately following an. operation of the. machine with a total key depressed if'such' key -isheld'depressed and therefore power .loof

cannotbe `applied to operate the machine in such circumstances.

' *Referring now to the improved means: for

automatically effecting the shift of 'control- .ling devices for the two counters l(see Figs.

.land 13), the lower4 arm of the lever 10 is connected by 'a link 21 Vto an arm'20loose' .upon a rock shaft 501. Mounted on this same rock shaft but `movable independently ofthe arm 20 is a ylever 22 having pivoted to 1ts upwardly'fextending arm -a cam-piece 23 which is connected by a spring 24'to thel hub of the lever. The actingportion of this4 cam takes the form of a' downwardly-pointed V andengages a roller stud 20fon the. arm 20. 'The lever 22 is` vibrated through snit'- ablegconnections presently to bedescribed and' forces the cam back and forth over the roller stud 20l so that the spring 24 will alternately act to cause-said cam to shift the 'arm 20 in opposite directions, thereby changing the adjustment of the lever 10. 'The advantage of lthe .particular `arrangement shown is that throughout practically' the entire swing of the lever 22 the adjustment of the controlling lever 10 remains unchanged and is in fact so held by the en ga ement of one side of the cam with the rol er stud 20F. Then when the said lever 22 is brought t o the end of its stroke in one direction the oint of the cam passes over the center of te said roller, whereupon the;

other side of the cam acts uponv the latter under the stress of the spring 24 which has been stretched inthe riding of the first side ofthe cam over the roller, and the result is that the arm 20'is then, but not until then,

lshifted in a uick and etlicient manner.

rIfhe vibration of the lever 22 is produced through its connection with a reciprocating bar 14 at the back ofthe machine, which bar corresponds with the similarly-designated bar in the VincentfBenner patent. It is here shown with a cam slot'14 engaged by a roller 15 on one arm 1'5b` of a lever whose other arm 15c is connected by a link 18 with thev lever 22. The arms 15b'and 15c are here shownv secured to opposite ends of a s ort i wheel 17" (Fig. 9)', but as an improvement upon the construction shown in said patent` I have devised v the following described means for controlling the actuation of said gearing. The gear wheel 17b is secured toa sleeve 30 looseon the familiar oscillatoryVv drive shaft 100 and there isv secured to this same lsleeve a ratchet wheel 31 adapted to be intermittently turned by a pawl 32 pivoted upon an arm 33 which is secured to said v shaft 100,engagement between the pawl fand the ratchet'w'heel being enforced by a spring 34, (see Figs. 6 to 8). Normally the arm 33 is forward and the pawl in engagement with a tooth of the ratchet wheel as shown by dotted lines in Fig. 6. When the oper` atin handle of the machine is pulled or the macine otherwise operated tooscillate the shaft 100 inits initial direction the pawl is carried back a distance beyond the shoulder` of the following tooth of the ratchet wheel and unless restrained from so doing comes to rest upon an intermediate inclined back of the next toot ready to advance against the shoulder of the tooth aheadwhen the arm 33 rocks forward with the return oscillation of the shaftl 100, such actioncausing the ratchet and connected gear wheel 17b to turn the proper distance for half rotating the crank 16 and thereby shifting the bar 14 from one extreme position to the other. It is desirable to lock the bar against movement except as, derived ortion of the from the shaft 100 and hence the sleeve 30 is formed or provided with a disk 35 having a series lof notches with radial sides, as

` clearly shown in Figs. 7 and 8, and a correspondingly formed ylu 36 on an arm37 normally engages onel o said notches to lock the sleeve and connected parts. Said arm 37 is pivoted at its rear end toa bracket on the base'casting of the machine and is connected at its forward end to said base casting by a spring 38 for enforcing engagement between the lug 36 and the notch. Said arm has fastened to one side of it at an intermediate point a plate 39 (see dotted lines, Fig. 6,) having a laterally-projecting lug 39 diamond-shaped in cross section, as shown in Figs. 7 and 8. The pawl 32 carries a laterally-projecting roller stud 32'* and when the pawl is retracted this stud rides up over said lug 39a 'and takes a position on the rear side ofthe same so that when the pawl is advanced and before it reaches the shoulder ofthe ratchet tooth ahead the roller stud Y acting upon the. oblique rear side of the lug' lwith a camming effect will force thel arm 37 up against the stress of the spring 38so that the lug 36 will be carried out of the notch in the disk 35, (Fig. 7), thereby unlocking the latter and connected parts, whereupon they ,l

arefree ton be actuated as above'explained through the turning'of theratchet wheel by the pawl. As the-pawl reaches the end of its stroke another notchf of the disk 35 arrives under the lug 36 and the latter snaps into it, the ,roller 32a havinI of course passed on forward ofthe lug 3 a. f Means are provided` for disabling at will the mechanism for reciprocating :the bar 14,

such means comprising a disk 60 .loose upon the sleeve 30 and having a raised segmental portion 60a normally retired from., a position where the roller stud 32 could reach it,

but adaptedvupon rocking of the disk to be brought up against the -lug39, -as shown in Fig-38, sothat its outeredge will constitute practically a continuation of theupper surface of the lug, from which it results that the roller stud havingpassed oversaid lug cannot drop behind itbut-willl ride-upon the vhigh outer edge of the disk and so will be prevented from engaging the ratchet wheel lwhen the arm 33 rocks forward.` Consequently there will be no actuation of the bar-reciprocating mechanism and the Asame will remain locked by the arm 37. 4Means for controlling the disk 60 comprise an arm 6 1 having a stud engaging a bifurcated project-ion of the disk, said arm secured to one end of a rock shaft 62; an arm 63 secured to the other end of said rock shaft, (see Figs. 6, 8 and 9); and 'a key stem 26 connected at its lower end tothe latter arm and carrying a key 25 at its upper end which protrudes through the keyboard.l A spring 268L normally upholds the key stem vVincent-Benner patent.

and the latter has a notch 26 to engage the upper keyboard plate when the key is "depressed and hold the same down.

ter for such engagement is somewhat modified as compared with that shown 'in the Thus instead of having the upright portion notched for engagement of the linger 7the bar carries a pair of pivotally-mounted arms 14b and 14c connected by a spring 14d, the arms extending on opposite sides of a limit-,stud 14e on the bar. This arrangement provides for a close engagement between thefinger and the coacting members on the barv and also for a cushioning effect in reciprocations of the carriage.

Passing now to the matter of line spacing it may first be said by way of premise that in order to .produce double c olumn printing with successively recorded amounts in horizontal alinement it is essential that there shall be line spacing only in every other operation of the machine and the Vincent-Benner patent shows ,ank arrangement for suspending the line spacing when the carriage rmoves to the right-hand position so that an amount having been printed in the left-hand column no line spacing ensues as the handle returns to normal. Similar mechanism is shown in the accompanying drawin s, the same comprising slide bars or strips 8, and 89 mounted on the back panel of the machine, the former having jaws 86 embracing the line spacing bail 84 and the strip or bar 89 having jaws 90 extending under the bail rod. The feed lever 92 (Fig. 1) engages an ear of the slide bar or strip 89 as usual and the latter has a beveled lug 96 (Fig. 11) for engagement with the similar lug of a coupler piece or dog 95 pivoted to the slide strip or bar 87 and actuated by a spring 97. As in the case of the corresponding coupler piece or dog in the Vincent-Benner construction there is an undercut or shouldered downward Aextension 95@l of the coupler pieceaganst which a stud carried by the reciprocating bar 14 is adapted to act so as to disconnect the slides 87 and 89 when the carriage shifts to the right',

l which means a shiftto the left of the bar 14 as viewed from the rear. cording to the present invention such stud is not in fixed position on the bar 14 as in the Vincent-Benner construction but is otherwise arranged in the manner and for the -purpose presently to be described.

Provision is made in the`Vincent-Benner construction for discontinuing at will the However, ac-

automatic reciprocation of the paper carsingle column and for such Work the carriage is required to be in the left-.hand one ofthe two positions it is capable of occupying when the reciprocating mechanism is active. Now by the present invention provision is made for doing single column work with the carriage in the other or right-hand position also and to this end the means for disconnecting the paper feed slide bars or strips 87 and `89 by the shifting of the bar 14 which accompanies move- .ment of the carriage to the right-hand position,jmay be disabled at will. This is the occasion for adopting a different arrangementthan that of a stud such as that designated 14f in the Vincent-Benner construction fixed in position on the bar 14.

It is proposed by the present invention, besides providing for renabling the line spacing mechanism of th'e carriage in the right-hand position, to provide for again disabling thesame should the means by which the renabling has been accomplished be released or restored to normal. On the bar 14 there mounted a longitudinallymovableslide piece 70, through slots formed in i-t and studs on the bar, and this slide piece has a depending portion with a stud 71 adapted to perform the function of the stud 14i in the Vincent-Benner construction, that is to say the function of disabling the line spacing mechanism when Athe carriage moves to the right, by operating upon the depending portion 95a of the coupler or ydog, 95 as illustrated in Fig. 11. The slide is connected to the bar by a spring 7 2 which is superior to the spring 97 so that this slide "does not change its position on the bar when its stud 71 strikes the coupler 95. However, the slide is designed to be moved back against the stress of its spring 72 whenever the operator desires to renable the line spacing mechanism with the carriage in the right-hand position. The before-mentioned key 25 serves the purpose,`its stem 26 having a rearward extension 26b coupled to an arm 73 which is secured to a Short shaft 74 in a bearing on the back panel of the machine, another arm 75 being secured to the rear end of said shaft and having a stud 76 at its lower end to act upon the slide 70. lVith the lcarriageZlin the left-hand position the slide is sor-rie distance away from the stud 76, as illustrated 4in Fig.A 3, but with the carriage moved to the right, that is to say with the bar 14 moved to the 'left as viewed from the rear, the end of the slide lies up close to said stud, as illustrated in Fig. 11. It iS obvious therefore that depression of the key 25 will result lin thrusting said s'lideto the right as thel parts are-viewed from the rear,

regain its position in operative 'relation to the lug 96 ofthe line spacingbar89, as illustrated in Fig. 12. The stud 71, however,

remains in engagement with the vertical.

' the coupler 95. Hence, notwithstanding the operator may have depressed the key he can resume double-column work without having disturbed the line spacing.' 0f course if, having depressed the key, the coupler 95 was not displaced by release of 'the key, line spacing would occur with the carriage in the right-hand position, which would result in leaving a space where there should be an item inthe left-hand column and the two imprints successivelyv made, first with the carriage in the right-hand position and then with the carriage in the left-hand position, would not be in horizontal alinement as they should be.
